1 Claim. (Cl. 299-102) This invention relates to the application of liquids in the nature of cleansers or preservatives to horizontal surfaces and, more particularly, to apparatus for spraying uniform coats of such liquids on the floors of houses and other buildings.

The most important object of the present invention is to provide apparatus in the nature of a spray head adapted for attachment to various liquid containers which apparatus or spray head is so constructed as to receive liquid from a container and to dispense the liquid evenly and uniformly over a wide area as the container is carried across a room.

A further important object of the present invention is the provision of a spray head having an elongated, perforated bottom wall from which liquid is dispensed and an irregularly shaped top wall provided with an offcenter neck for receiving liquid from a container, the

length of the head and the location of the neck being such that the head may be moved readily and easily be neath obstructions or along a wall.

Other, more minor objects will become apparent in the specification which follows and from a study of the appended drawing wherein:

Figure 1 is a side, elevational view of the spray head of the present invention, parts being broken away and in section to reveal details of construction.

Fig. 2 is a bottom, plan view, parts being broken away and in section for clarity.

Fig. 3 is an enlarged, sectional view taken on line III- III of Fig. l; and

Fig. 4 is an enlarged, sectional view taken on line IV- IV of Fig. 1.

Referring now to the drawing, wherein like numerals indicate similar parts, there is illustrated a spray head including, as elements thereof, a hollow body 12, a coupler 14 and a bottom wall 16.

The body 12 is longitudinally V-shaped and has a pair of spaced, substantially parallel side walls 18 and 20 which are integrally joined by a top wall 22. The top wall 22 has a neck 24 formed therein at the point of convergence between long section 26 and short section 28 of top wall 22. The neck 24 is therefore situated adjacent one end of the elongated body 12. A transverse brace 19 interconnects the walls 18 and 20 intermediate the ends of body 12.

At its uppermost end, the neck 24 is internally threaded as at 30 and also rotatably receives an internally threaded coupler 14. It is obvious that any equivalent means of adapting the spray head 10 for coupling with a liquid container such as a conventional garden sprinkler may be employed on the neck 24. There is a washer 31 provided in coupler 14 for sealing the joint between neck 24 and a container.

At its lowermost, open end, the body 12 receives the elongated, rectangular, perforated bottom wall 16 which may be rigidly attached in closing relationship thereto in any suitable manner. Viewing Fig. 2, it is noted that c ICTQV the perforations in bottom Wall 16 are relatively small and dispersedsubstantially-throughout the area of the bottom wall 16. I

One of the important constructional details of the spray head 10 of the present invention is the requirement that the cross-sectional area of neck 24 be greater than the combined areas of the perforations of bottom wall 16 so that the volumetric flow through the neck 24 will normally be greater than the flow through the perforations of the bottom wall 16.

Since the containers with which the spray head 10 is adapted for use vary widely in size and shape, the container often projects laterally beyond thespray heads now in use and, therefore, necessitates movement of the spray head away from the desired horizontal spraying position as obstructions are encountered along the wall of a room or the like above the floor being coated. Similarly, it has been found diflicult to reach the area beneath certain obstructions. When the spray head 10 of the present invention is used in these and analogous situations, the off-center location of neck 24 is such that the long end of body 12 projects outwardly beyond the usual container and may, therefore, be carried across a room bottom wall 16 away from its horizontal position to clear obstructions. Likewise, the long end of body 12 is rel- .atively shallow and may, therefore, be moved beneath obstructions such as radiators.

In operation, the neck 24 is coupled with a liquid container which has been filled with the desired cleanser or preservative so that, when the container is tipped, the liquid will flow through the neck 24 into the interior of body 12. Since there is a greater flow through the neck 24 than through the perforations of the bottom wall 16, there will be a liquid level in body 12 above bottom wall 16 as long as there is liquid in the container and as long as the bottom Wall 16 is kept substantially parallel with the floor being sprayed. At the same. time, there is an air pocket within body 12 above this liquid level which equalizes the pressures within body 12 and insures that liquid is dispensed equally from all areas of bottom wall 16 despite the off-center location of neck 24. Thus, an even floor coating equal in width to the length of the bottom wall 16 may be accomplished each time the spray head 10 of the present invention and the container to which it is attached are carried across the area to be coated. I

It is obvious that the embodiment herein disclosed is a preferred form only and that many changes or modifications may be made therein without departing from the broad principles of the present invention. Such changes or modifications are contemplated hereby and it is, therefore, desired to be limited only by the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

In apparatus for applying a uniform coat of liquid flowing by gravity from an inverted container having a single opening to horizontal surfaces, a spray head comprising an elongated, inverted, substantially V-shaped, hollow body having an elongated, uniformly perforated, normally horizontal bottom wall, a pair of spaced, substantially parallel, normally upright, substantially triangular side walls, a pair of angularly converging top wall sections, and a tubular neck merging with said top wall sections therebetween and with said side walls adjacent the uppermost vertices of the latter and extending upwardly therefrom in a normally vertical direction, one of said top wall sections being at least substantially twice as long as the other, the internal cross-sectional area of the neck being greater than the combined areas of the coupling means on the necking adapting the spray head a for direct attachment to said container with the neck in communication with said opening of the container;
